This invention relates to improvements in liquid fuel burners and pertains particular ly to an improved type of 011' burner.

The primary ob]ect ofthe present inven 5 tion is to provide an oil burner for the burningof heavy OIlS, whereln' the Oll is vaporized and wherein water is vaporized, the

vapor of the oil and the water being so mixed and burned that the formation of soot is I greatly reduced and the creation of smell which usually results froin the burning of crude oils, is prevented.

Another object of the invention is to provide an oil burner having an improved and novel type of burner unit onto which the oil' only a portion of the area" thereof will be in use durin the operation of the burner. By

rotation of the unit new areas thereof may be arranged .to receive 011 while tl e areas 30 which have already been used are being freed.

of any deposit which may have formed there. on, the shifting or rotation of the unit being effected without removing the unit from the stove or heater in which it is mounted.

Other objects and advantages of the invention will become apparent as the description ofthe same proceeds and the invention will be best understood from a consideration of the following detailed description taken in connection with the accompanying drawings forming part of this specification, wlth the understanding, however, that theinvention is not confined to any strict conformity with theshowing'of the drawings butmay be 7 changed or modified so long as such changes or modifications mark no material departure from the salient features of the inven tion as expressed in the appended claims.

Figure 3 is a sectional View taken on the line 33 of Figure 2.

Figure 4 is a view showing the application of the oil burner embodying the present invention to a portable stove.

Referring more particularly to the drawings wherein like numerals of reference indicate corresponding parts throughout the several views, the numeral 1 indicates gens erally a stove of the coal or wood range type wherein the top 2 is provided with a num: ber of removable lids 3, certain of these lids closing openings through which access is had to the stove fire box 4.

For the installation of the oil burner emhodying the present invention one of-the lids 3 which covers an opening to the fire. box of the stove is provided with a pairof apertures through which pipes, hereinafter specifically designated, are run to the burner unit of the device as shown in Figure 2. t

The burner comprises *an oil feed pipe 5 which has one end directed upwardly and terminating in a receiver 6 here shown as in the form of a funnel while the other end has an inclined portion which is coupled with the laterally directed arm of a threeway coupling 7. The other two arms of the coupling 7 are inclined slightly from the vertical as shown and the lower one is connected through the medium of a nipple 8 which passes through one'of the apertures. in the plate 3, with oneof the aligned arms of a second three-way coupling 9. I

' The upper end of the coupling 7 has a plate 10 thereon through which passes a rod 11, this rod extending downwardly through and beyond the lower end of thecoupling 9 and terminating in a point 12 as shown. The upper end of the rod 11 has. a head 13 and disposed between this head and the plate 10 is a spring 14.

From the description thus far given 1t will be seen that the couplings 7 and 9 are so arranged and supported by the pipe 5 as to extend in a line which is inclined or tllted slightly from the vertical so that the other eral arm of the coupling 9, while the other end has secured thereto one arm of a right angle union or coupling 18, the other arm of which is directed upwardly as shown.

The coupling 16 has connected thereto a water conducting pipe 19 which extends upwardly through the other aperture of the plate 3 and joins a pipe 20 in which a U- bend 21 is formed to provide a trap. The other end of this pipe 20 is connected with an upwardly directed pipe section 22 which terminates at its upper end in a funnel 23.

lVithin the firebox 4 there is aburner plate which is indicated generally by the nu meral 24. of circular configuration and has an upstanding rim or fiange 25 formed about its edge, the central portion being provided with a threaded opening 26 in which is threadably engaged one end of ashort pipe or tube. 27, the other end of which is extendedinto the upwardly directed end of the coupling-18 in the manner shown sothat the burner plate will be supported upon this coupling and will be prevented from slipping or being accidentally moved therefrom by this tube.

The tube 27 is of materially less over-all diameter than the interior diameter of the end of the coupling into which it extends and in order'to maintain the tube centered the inner wall of the upwardly directed portion of the coupling 18 is provided with several lugs 28 against which the outer surface of the tube" abuts. The central part of the plate 24 is provided with an annular wall 29 which surrounds and is concentric with the opening 26 through which the tube 27 .extends so that the burner plate is divided into a ce'ntral cup 30- and a. surrounding relatively broad channel 31.

As shown in Figure 2 the rod 11 reaches down to theburner plate 24 so that the lower end or point 12 thereof may be brought into contact with the surface of the annular portion 31. This rod 11 fits loosely in the couplings 7 and 9 and the nipple 8 through receiver or This. burner late is ureferabl which it passes so that considerable lateral motion is permitted to facilitate the rotat1on of the plate 24 thereby. By pressing downby the numeral 32 while the water receptacle is indicated by the numeral Each of these receptacles is provided with a faucet 84. The faucet upon the oil tank 32 discharges into the receiver 6 upon the end of the oil pipe 5 while the faucet on the tank 33 discharges into the receiver 23 upon the water pipe 20.

In operation the faucets 34 are regulated to drip the oil and water into their respective receiving funnels, some of the oil having been run onto the burner plate 24 and ignited before the water is turned 011. Due to the angle at which the parts are disposed in the fire box it will be seen that the burner plate is also supported at an inclination, the lowest point thereof being substantially diametrically opposite the area directly behind the point where oil falls thereon from the discharge arm of the coupling 9..

After a suificient quantity of oil has dripped from the discharge arm of the coupling 9 onto the annular portion 31 of the burner plate to flow to the opposite or lowest point thereof so that substantially half of the area of the annular portion is coveredwith oil, the oil on the plate is ignited and the flame thereof is, of course, continua lly fed by the oil flowing from the discharge pipe. Atter the oil has burned a sufficient length of time to thoroughly heat the surrounding elements the water is then permitted to flow slowly into the pipe 15 where it will be converted into steam due to the heated condition of this pipe and this steam will pass upwardly through the tube 27 into the cup 80. As the'pipe 27 and, of course, the plate 24 will be in a highly heated state the steam generated in'the pipe 15 will be superheated as it comes into'contact with these parts and will enter the cup 30 in a superheated dry condition to mix with the flame of the burning oil and the addition of the oxygen content of this super-heated steam to the burning oil will cause-the oil to be praclie tion of the burner plate receives an amount of carbon which would interfere with the proper burning of the oil the rod 11 may be depressed until the point is brought into 0011+ tact with the surface of the plate and then' oscillated so as to use the lowerend thereof for turning the plate on the coupling 18. Thisoperation is carried on until the plate has been given a half turn so that an unused portion of the channel will be brought into position to receive oil from the oil discharging line. The carbonremaining on theused half of the plate willbe burned off during the use of the new section which has been turned into position to receive a supply of oil. The necessary air draft for the operation of the burner is provided through the aperture 41 formed through the plate 8 from which the burner structure is suspended.

In Figure 4 there is shown the application of the burner structure embodying the present invention to a portable heating stove, the stove being indicated generally by the numeral 35. The top of the stove 35 is provided with a bar 36 which is suitably secured thereto, each end of which bar is turned upwardly and inwardly to form the supporting bracket arm 37. Upon one of these arms the water tank 38 is mounted, while upon the other the oil tank 39 is mounted and each of these tanks has a faucet d0 like the tanks 32 and 33, eachv of which discharges into a receiving funnel 39 located therebeneath. It is, of course, understood that the structure within the stove 35 is a duplication of the structure shown in Figure 2, therefore, details of the same have not been shown.
